I planted seeds from marigolds I grew from a previous season. They are all orange. What should I do to get more color from the marigolds?

If the parent plants were not orange and their seeds grow orange plants, then they were probably hybrids that revert back to orange when grown from seed. Some breeders develop the flowers this way to keep their variety exclusive. If you would like to grow marigolds from seed that stay multi-colored, you will need to find a multi-colored, non-hybrid variety and collect seeds from those plants.
